Data Processing Method, Non-Transitory Computer-Readable Storage Medium, and Data Processing Device

1. A data processing method executed by a computer, the data processing method comprising: specifying a first region range from a data table including a plurality of input regions arranged in a first direction and a second direction, a first region range being a plurality of numerical value regions which are continuously disposed in the first direction, each of the plurality of numerical value regions being an input region in which a numerical value is input, a plurality of numerical values input in the plurality of numerical value regions satisfy a predetermined condition that a difference between a calculation result of a calculation using the plurality of numerical values and a specified numerical value input in an adjacent region adjacent to the first direction is less than a predetermined threshold; specifying a second region range from the data table, the second region range being located at a position where the first region range is translated in the second direction, the second region range including at least one character string region in which a character string is input and at least one blank region in which any value is not input; associating the character string and each of the plurality of numerical values; and outputting data that indicates a correspondence between the character string and each of the plurality of numerical values based on the associating.

2. The data processing method according to claim 1 , wherein the calculation result is a sum of the plurality of numerical values or a product of the plurality of numerical values; and wherein the first region range is specified by solving a subset sum problem or a subset product problem for the plurality of input regions in the data table.

3. The data processing method according to claim 2 , wherein the first region range is specified by fixing the adjacent region sequentially and by using a binary search.

4. The data processing method according to claim 2 , wherein the first region range is specified by deleting the specified first input range in the data table and repeating a processing of the specifying until the first input regions is no longer specified.

5. The data processing method according to claim 1 , wherein the first direction and the second direction are at right angles to each other.

6. A non-transitory computer-readable storage medium storing a data processing program that causes a computer to execute a process comprising: specifying a first region range from a data table including a plurality of input regions arranged in a first direction and a second direction, a first region range being a plurality of numerical value regions which are continuously disposed in the first direction, each of the plurality of numerical value regions being an input region in which a numerical value is input, a plurality of numerical values input in the plurality of numerical value regions satisfy a predetermined condition that a difference between a calculation result of a calculation using the plurality of numerical values and a specified numerical value input in an adjacent region adjacent to the first direction is less than a predetermined threshold; specifying a second region range from the data table, the second region range being located at a position where the first region range is translated in the second direction, the second region range including at least one character string region in which a character string is input and at least one blank region in which any value is not input; associating the character string and each of the plurality of numerical values; and outputting data that indicates a correspondence between the character string and each of the plurality of numerical values based on the associating.

7. A data processing device comprising: a memory; and a processor coupled to the memory and the processor configured to: specify a first region range from a data table including a plurality of input regions arranged in a first direction and a second direction, a first region range being a plurality of numerical value regions which are continuously disposed in the first direction, each of the plurality of numerical value regions being an input region in which a numerical value is input, a plurality of numerical values input in the plurality of numerical value regions satisfy a predetermined condition that a difference between a calculation result of a calculation using the plurality of numerical values and a specified numerical value input in an adjacent region adjacent to the first direction is less than a predetermined threshold; specify a second region range from the data table, the second region range being located at a position where the first region range is translated in the second direction, the second region range including at least one character string region in which a character string is input and at least one blank region in which any value is not input; associate the character string and each of the plurality of numerical values; and output data that indicates a correspondence between the character string and each of the plurality of numerical values based on the associating.
